ROLLING WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 566,284, dated August 18, 1896.

Application filed March 19,1896.

To aZZ whom it ntcty concern:

Be it known that I, SAMUEL l-I. CASSEL- BERRY, a citizen of the United States, residing at Oollegeville, in the county of Montgomery and State of Pennsylvania, have i11- vented certain new and useful Improvements in Rolling WVindow-Screens; and I do hereby declare that the following is a full, clear, and exactldescription of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to that class of rolling window-screens which embody a screen fabric mounted upon a spring-roller and adapted to be detachably connected with the sliding sash.

The object of my invention is to provide a simple and improved screen of this character in which the edges of thescreen fabric will be more securely and effectually retained in position, and which will furthermore possess advantages in point of convenience, ease of operation, adj ustability, effectiveness, and general efficiency.

In the drawings, Figure 1 is a perspective view showing the screen in raised position. Fig. 2 is an end or edge elevation. Fig. 3 is a detail Vertical sectional view taken on the line 1 1, Fig. 1. Fig. aisadetail vertical sectional View taken on the line 2 2, Fig. 1. Fig. 5 is a detail perspective view illustrating the arrangement and operation of the side retaining-strips. Fig. 6 is a detail horizontal sectional view taken on the line 3 3, Fig. 1, showing the screen fabric clamped in position. Fig. 7 is a corresponding view illustrating the passage of the side extensions of the top strip with relation to the side securing-strips. Fig. 8 is a detail horizontal sectional view taken on the line 4 4, Fig. 1. Fig. 9 is a transverse horizontal sectional view taken on the line 5 5, Fig. 1.

Referring to the drawings, A designates the window frame or casing, and B the lower sash of the same.

0 designates a spring-actuated roller mounted at the lower end upon the window sill or face of the casing and carrying the flexible screen fabric D.

The screen fabric D is extended at its side edges, as shown at d cl, so that it will project serial No. 583,931. (No model.)

over the face a a of the window frame or casing A, the relative width or transverse size of the screen being thus greater than the window-opening. At its top the edge d is bound between the inner and outer members E and E respectively, of a top strip E. The strips E and E are securely fastened or bound together. The top strip E thus can ries the upper edge of the screen fabric and extends transversely and horizontally across the window, the inner member or strip E being of a length corresponding to the space between the vertical side beads a a of the window-frame and traveling between the same, while the outer member or strip E is extended at its ends, as shown at e 6 so that it corresponds in width to the screen fabric D and has its ends 6 e projecting over the face of the window-fran1e.

Upon the top strip E are provided screweyes f f, projecting vertically and adapted to be engaged by hooks g g, provided upon the bottom stile or cross-piece b of the sash. These hooks are preferably pivotally mounted, so that they will rest in flat position with relation to the sash and swing in a longitudinal plane with relation to the cross-bar I), while the screw-eyes f are preferably relatively mounted in transverse position with relation to the line of travel of the screen. Upon the top strip E is also preferably provided a projecting knob h, by which the screen may be raised or manipulated to effect the connection of the screw-eyesfwith the hooks g.

I designates side strips of suitable length mounted in vertical position upon the face a a of the window frame or casing and with relation to the side edges 61 d of the screen, which project over the face of the window frame or casing. These strips are adapted to move inwardly and outwardly with relation to the face a of the window-casing to permit the passage of the projecting ends 6 e of the outer member or strip E of the top strip E between said movable binding-strips I I and the face of the window-casing in the adjustment of the screen, and also to enable the clamping or binding of the projecting side edges 61 d of the screen between said bindingstrips I I and the face of the windowcasing when the screen is in adjusted position. In thus mounting the movable side bindingstrips I I upon the face a a of the windowcasing I prefer to provide said strips at their upper and lower ends with openings or perforations 2', through which pass headed pins or nails J, horizontally arranged and projecting from the face of the window-casing, the binding-strips being thus mounted and adapted to slide upon said headed pins and the latter being of sufficient length to permit the proper sliding movement of the strips. hen the binding-strips I I are at their outward limit of movement, the projecting ends e e of the top strip will pass readily between the binding-strips and the face of the windowcasing, and when the screen is in adjusted position the binding-strips are pushed in so that they will securely bind or clamp the free projecting side edges (Z (Z of the screen fabric or netting against the face of the windowcasing.

To retain the strips I I in binding or clampin g position, I provide suitable thumb-buttons or clamps J pivotally mounted with relation to the strips and adapted to be turned to securely clamp the strips against the face of the windowcasing.

The operation and advantages of my inven tion will be readily understood.

By reason of my improved construction and arrangement of parts, the objection usually experienced in flexible rolling window-screens of this class pulling out from edge guides and bellying at the center in stormy weather is effectually obviated. The projection of the side edges of the flexible screen-netting over the face of the windowcasin g and the clamping of the same against the face of the casing by the movable side binding-strips, in connection with the general construction and arrangement of parts as embodied in my invention, provides an effective screen of this type in which the side edges of the flexible screen fabric are securely bound or retained in position against the face of the window-casing.

By reason of the improved construction and arrangement of parts as embodied in my invention, it will be noted that the screen can be lowered or raised and adjusted independent of the sash, or the sash and screen can be operated together in the usual manner.

Having thus described my invention, I claim and desire to secure by Letters Patent- 1. An improved rolling Window-screen of the class described, comprising, in combination with the window frame or casin g and the sash, the flexible rolling-screen fabric having the extended side edges 61 d projecting over the face of the window-casing, the top strip embodying the inner member or strip adapted to operate between the sides of the windowcasing and the outer member or strip having the extended ends 6 e projecting over the face of the window-casing and corresponding to the projecting side edges cl d of the screen fabric, the screw-eyes upon said top strip and the engaging hooks upon the sash, and the vertical movable side strips mounted upon the face of the window-casing and adapted to slide upon the headed pins projecting therefrom, said side strips being adapted to move inwardly and outwardly with relation to the face of the window-casing to clamp or bind the projecting edges 01 d of the screen fabric against the face of the casing, the casing being provided with thumb-buttons for clamping the strips in position, substantially as and for the purpose set forth.

2. The hereindescribed improved rolling window-screen, comprising, in combination with the window frame or casing and the sash, the flexible screen fabric D having the extended side edges 01 (Z projecting over the face of the window-casing,the spring-actuated roller 0 to which the lower end of the screen fabric is secured, the top strip E embodying the inner strip or member E adapted to operate between the sides of the window-casing and the outer strip or member E having the extended ends 6 e projecting over the face of the window-casing and corresponding to the extended side edges dof the screen fabric, the screw-eyes upon said top strip and the engaging hooks upon the sash, the verticallymounted clamping-strips I adapted to move inwardly and outwardly with relation to the face of the window-casing upon the headed pins J projecting from the casing, and the thumbbuttons J for clamping said movable strips against the face of the casing, said bindingstrips being adapted to clamp or bind the projecting side edges of the screen fabric against the face of the window-casing, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

SAMUEL II. CASSELBERRY.
